"comma (o1. ro se) object is the provision of such a padlock whichaifords great security, and which allows location. of the locking andother mechanical parts in a manner rendering them virtually.inaccessible to moisture andother foreign elements which might interferewith their operation, despite the provision ofno special protectingmeans therefor.

Another object is the provision of an improved padlock having a bodycomprising a pair of relatively massive slidable portions carryingcooperating shackle-forming sections, and in which the shackle soformed, when locked, is secured at both ends against twisting.

rther objects and advantages will be apparent from the followingdescription wherein referonce is made to the'accompanying drawingillustrating a preferred embodiment of my invention' and wherein similarreference numerals designate similar parts throughout'the several views.

In the drawing: Figure 1 is a view principally in sectional elevation,but partly in side elevation, of a lock incorporating the principles ofthis invention, showing the same closed. 7 Figure 2 is a similar viewshowing the lock partly opened, a greater proportion thereof beingillustrated in side elevation.

Figure 3 is an end elevational view of the lock in closed position,partly broken away; Figure 4 is a bottom view of the lock, and Figure 5is a detailed perspective view of the lock cylinder and bolt assembly.

Referring now to the drawing it will be seen that the lock consists oftwo principal parts,

iii, l5, longitudinally slidable with relation to each other. Theportion H3 carries the principal shackle portion 52, which comprises apartly circular inverted hooksection, while the portion 15 iscooperatively formed at its upper end to complete the circular shackleopening, 'and slidable downwardly to free the 'end of the shackle hook,which isprovided with a lug portion ll adapted to fit into a recess Itin top of the downwardly slidable block-like body portion P5.

The plane of cleavage between the cooperating body portions lQ-ltiisdesignated 20, anda dovetailed connection is provided between the parts,a headed tongueportion as It carried by portion [5 being slidable in aconformably in body la A spring 21 trapped in the faceof the; lock boltforsuch purpose. lock cylinder is of course rotatable by means of a ,key(not shown), and the bolt, until member.

trapped in aligned openings in the tongue" shapedaperture in the bodyportion iii; A spring section 55 and in the body section directlythereabove, urges the block portion l5 downwardly to free the end of theshackle hookwhen the 1 lockbolt 25 is retracted to permit-such sliding"inovement. The bolt is laterally slidable in block i5into and out ofengagement with an opening block iii behind the lock bolt tends 'toproject the bolt, which is retractable by means of a lock cylinder itprovided with an eccentric pin 3i engaging a slot .25 provided in thebottom .The

it is released in the manner described, holds the block portion itin'the lockedposition shown in Figure l, in which it closes the end ofthe shackle. A pin 33 projecting through the side of the body and into.a slot 36 in the tongue portion Q It limits the sliding movement of theparts. WhatIclaim i'sz. i 1.
